Study into public sector overmanning unveils two identical Prime Ministers

An investigation into duplication in the public sector has exposed two identical public school boys doing the prime minister's job - each on full wages.
Further probing found that the nation now has two parties in power, and only one in opposition.
But two government spokespeople denied there was overmanning in Downing Street. 'What absolute nonsense,' said one, 'We run a very tight ship and we're all aware that everyone in Britain is in this together. Aren't we?'
'Yeah,' added the other press officer.
